I don’t think the organization has released much injury info at all. For example, Walsh hasn’t pitched in 2 weeks for Springfield, yet is not on the injured list. And he was pitcher of the month for May.
The fact that not much injury info is being made public is not really unusual. The Cards keep that info pretty close to the vest. I can see where that would be helpful so other organizations don’t know all your business! I am very interested to see how the organization deals with the pitching crisis and what trades will happen and who is included in those trades!
